Such services shall protect the personal liberty of the individual and shall be provided with the least restrictive conditions necessary to achieve the purposes of the treatment, services, or supports.

(2) A right to dignity, privacy, and humane care. To the maximum extent possible, treatment, services, and supports shall be provided in natural community settings.
